The 49ers have signed former Broncos safety Darcel McBath to a one-year contract, filling out their 90-man training-camp roster and adding depth to a position that could be without the franchise-tagged Dashon Goldson when veterans report for camp Thursday.

McBath, 26, Denver’s second-round pick in 2009 (No. 48 overall), played in 20 games with the Broncos from 2009-10. As a rookie, he led the team in special-teams tackles (11) – becoming one of four rookies to lead their team in that category – and had two interceptions. He was waived by Denver after last year’s final preseason game and signed by the Jaguars in December. He appeared in one game with the Jacksonville and was released in April.

McBath’s position coach in Denver was 49ers secondary coach Ed Donatell. In March, San Francisco signed cornerback Perrish Cox – a fifth-round pick of the Broncos in 2010 who was also coach by Donatell.

McBath was a teammate of wide receiver Michael Crabtree for three seasons at Texas Tech where he earned first-team All-Big 12 honors in 2008.

* The 49ers have placed a pair of rookies, running back Jewel Hampton and guard Joe Looney, on the non-football injury list, according to FOXSport’s Aaron Wilson. They have also placed rookie linebacker Darius Fleming on the physically unable to perform list. Fleming is expected to miss the season with a torn ACL.

Looney and Hampton aren’t eligible to return to the roster until Week 7, at the earliest. Looney, a fourth-round pick, suffered a foot injury at the Senior Bowl in January. Hampton suffered a pair of ACL injuries – one to each knee – in college. Looney and Hampton will count against the roster limit during training camp. They won’t count against the roster when the 49ers cut down to 53 players.
